FutureWarning: Method .ptp is deprecated and will be removed in a future version. Use numpy.ptp instead.

Hello! It seems like you are encountering a FutureWarning related to the method `.ptp`. This warning is letting you know that the method `.ptp` will be removed in a future version of the software you are using, and you should instead use `numpy.ptp` for the same functionality.
To fix this warning, you can replace the usage of `.ptp` with `numpy.ptp`. Here's an example:
```python
import numpy as np
# Assuming you have an array called 'data'
range_value = np.ptp(data)
```
By using `numpy.ptp`, you can avoid the warning and ensure compatibility with future versions of the software. Let me know if you have any further questions!

'numpy.ndarray' object has no attribute 'pop'. Did you mean: 'ptp'?
这个错误提示表明你正在尝试使用一个numpy数组的pop()方法,但是该方法不存在。相反,它建议你使用ptp()方法。ptp()方法返回数组的最大值和最小值之间的差异。如果你确实需要删除数组中的元素,你可以使用Python内置的pop()方法。下面是一个例子:
```python
import numpy as np
# 创建一个numpy数组
arr = np.array([1, 2, 3, 4, 5])
# 使用Python内置的pop()方法删除最后一个元素
arr = np.delete(arr, -1)
# 输出删除后的数组
print(arr)
# 使用ptp()方法获取数组的最大值和最小值之间的差异
diff = np.ptp(arr)
# 输出差异
print(diff)
```
Failed to start ptp4l.service: Unit ptp4l.service not found.
这个错误提示意味着系统在启动ptp4l服务时找不到ptp4l.service这个单元。ptp4l是Linux系统中的一个用于PTP协议实现的应用程序,可能是由于该应用程序未正确安装或配置,或者该应用程序的服务单元文件被删除或移动所导致的。如果您需要使用ptp4l服务,请确保已正确安装和配置它,并检查该服务的单元文件是否存在。您可以使用命令systemctl status ptp4l.service来查看该服务是否存在,并使用apt-get或yum等包管理器安装缺失的软件包。如果您不需要使用ptp4l服务,您可以忽略此错误提示。
